Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to a blind slat assembly
for door/window Venetian blinds wherein left/right side brackets of
a door/window frame are provided with a plurality of retaining
holes at the corresponding inner sides thereon respectively for
blind slats to be mounted thereto, and a linkage rod is mounted at
the same side of the blind slats thereon; whereby, via the
flexibility of the blind slats thereof, each blind slat is capable
of being pushed at both lateral sides thereof till slightly bent
into an arc shape at the middle section thereof, permitting
protruded coupling sections extending at both ends of a central
locating rod of the blind slat thereof to detach from the retaining
holes of the left/right side brackets according to the deformation
of the blind slat thereof. Thus, the blind slat is retrieved in a
fast and easy manner for the replacement of a new blind slat
assembled in the same way above without the door/window frame being
troublesomely dismantled in the operation thereof, facilitating an
easy and speedy dismounting as well as assembling of the blind
slats for variation and replacement thereof.
[0002] Please refer to FIG. 1. A conventional blind slat assembly
for door/window Venetian blinds include a door/window frame 10 made
up of a plurality of side brackets 11 mounted into a frame body, a
plurality of retaining holes 111 disposed at the corresponding
inner sides of the left and right side brackets 11 thereon for
pivotal posts 121 protruding at both lateral sides of each blind
slat 12 to be registered therewith so as to locate the blind slats
12 onto the door/window frame 10 thereof, and a linkage rod 122
attached at the same side of the blind slats 12 to actuate the
blind slats 12 synchronically upwards or downwards in the folding
or unfolding operation of the Venetian blind thereof for sheltering
effect thereof.
[0003] There are some drawbacks to such conventional blind slats
for door/window Venetian blinds. Most of all, to dismount the blind
slats 12 from the door/window frame 10 for variation of different
styles or replacement of new ones, each of the side brackets 11
must be individually dismantled to detach the left/right side
brackets 11 from the blind slats 12 thereof before new blind slats
12 are assembled onto the door/window frame 10 thereof, which is
both troublesome and time-consuming in the operation thereof.
SUMMARY OF THE PRESENT INVENTION
[0004] It is, therefore, the primary purpose of the present
invention to provide a blind slat assembly for door/window Venetian
blinds wherein, via the flexibility of blind slats, each blind slat
is capable of being pushed at both lateral sides thereof till
slightly bent into an arc shape at the middle section thereof,
permitting protruded coupling sections extending at both ends of a
central locating rod of the blind slat thereof to detach from
retaining holes of left/right side brackets of a door/window frame
according to the deformation of the blind slat thereof. Thus, the
blind slat is retrieved in a fast and easy manner for the
replacement of a new blind slat without the door/window frame being
troublesomely dismantled in the operation thereof, facilitating an
easy and speedy dismounting as well as assembling of the blind
slats for variation and replacement thereof.
[0005] It is, therefore, the second purpose of the present
invention to provide a blind slat assembly for door/window Venetian
blinds wherein each blind slat thereof is integrally molded without
any other processing and directly mounted onto the left/right side
brackets of the door/window frame, effecting a qualified production
of the blind slats in an easy and speedy manner so as to boost the
competitive power of the present invention in the market.

door/window frame 20 is made up of a plurality of side brackets 21
wherein the left and right side brackets 21 thereof are
respectively equipped with a plurality of retaining holes 211
disposed at the corresponding inner lateral sides thereon. The
blind slat 30, a flexible member with proper hardness and thickness
that is capable of being elastically twisted and deformed, is made
up of a plurality of bamboo rods 31 closely juxtaposed one by one
in abutment and properly woven at preset spots to form a bound slat
body. A thicker locating rod 32 is disposed at the center of the
blind slat 30 thereof, and a protruded coupling section 321 is
extending at both ends of the central locating rod 32 thereof
respectively to be registered with the retaining holes 211 of the
left/right side brackets 21 thereby. A linkage rod 33 is attached
at the same side of the blind slats 30 assembled.
[0014] Please refer to FIGS. 3 to 4 inclusive. In assembly, the
protruded coupling sections 32 extending at both ends of the
central locating rod 32 of each blind slat 30 are respectively
registered with the retaining holes 211 of the left/right side
brackets 21 thereof, permitting the blind slats 30 to be located at
the left/right side brackets 21 of the door/window frame 20
thereon. The side brackets 21 are sequentially mounted to form the
door/window frame 20 thereof, and the blind slats 30 are
